Captain: "Look here, Corporal, you know the great object of the new system is to train the N.C.O.'s to act on their own initiative and responsibility. Now I want you to take a couple of men—understand? Two men, and advance along the main road and select a position commanding a good view of the road, where your sentry can see without being seen—understand? Now you should choose if possible a place giving some shelter for your men, as you are to imagine you've got to occupy it for twenty-four hours, and it ought to be so chosen that you could offer a certain amount of resistance if attacked—understand? You're in absolute command, and you are to do whatever you think best under the circumstances, keeping in mind the object for which you were sent out—understand?"
